The present invention relates to an apparatus designed for use with a furnace or the like and has for its prime object to provide means for heating and humidifying air.

Another very important object of the invention resides in the provision of an apparatus of this character which utilizes the heat from the tion.

A still further very important object of the invention resides in the provision of an air heating and humidifying apparatus which is exceedingly simple in construction, inexpensive to manufacture, thoroughly efficient and reliable in use and operation, durable, and otherwise well adapted to the purpose for which it is designed.

lVith the above and numerous other ob-- jects in view as will appear as the description proceeds, the invention resldes 111 certain novel features of construction, and inand claimed.

In the drawings: 7

Figure 1 is a side elevation of the apparatus embodying the features of my invention.

Figure 2 is a vertical section therethrough, and

Figure 3 is a top plan view of the water pan. 7

Referring to the drawings in detail it will be seen that the numeral 5 denotes a hot 'air furnace or the like from which extends a pipe 6 for taking off the products of combustion. Pipe 7 represents the means used for taking off the heated air. The parts thus far described are not of the essence of my invention but have been illustrated merely to gaseous products of combusin the bottom of the pan and a 14 ex-"- I tends through this collar terminating a slight distance above the pan and leads to asource of fresh air such as to theexterior of the building in which the apparatus is installed. The bottom edge of the section 8 rests in an annular groove in the base ring 1 5.

Pipe 6 is attached to or merged into a pipe 6 which extends through the section 9 and is then ofi'set downwardly as at 16 and merges into a lower horizontal section 26 which extends through an opening in the section'9 and over the end of the lower section 26 the-re is disposed a suitable closure 17. Pipe 2'! rises from the lower sectionQGthrough the top 10 merging into an elbow 28 from which extends a'pipev 29 to the chimneystructure' 30. A pipe 31 rises from an opening in the top 10 to a register 32. A pipe 33 rises from an opening in the top 10 to a register. 34 to which the pipe 7 also extends. This arrange{ ment of utilizing the hot air, of cou'rse, is not of the essence of the invention but has;

been illustrated as practical exemplification.

It will be readily apparent that the prod-f nets of combustion from the furnace must pass through the pipes 6, 6" and through the pipe 27 and of course will heat the airfin the drum and this air will be moistened by a,

the water in the pan 11 and the air in the. drumwvill be supplied through the pipe 14; ittlld will rise through pipes 31 and 83 or the A very important feature of this invention is in the manner of supplying waterto the pan 11, and in this connection, it will be seen that the water from any suitable source of supply is fed through a pipe 35 equipped exteriorly of the drum with asuitable valve, and at its outlet end extending through the wall of the section 9. On its inner end, the pipe 35 is provided with'a spray nozzle 36 so that,as is apparent the water is supplied to the pan 11 in the form'of a fine spray or mist, thus furnishing immediately the humidity to the air passing through the drum. Such means permits comparative simplicity in constructionand easy regulation or control of the device.

has been described in considerable detail' extending through the pan'and terminating the bottom thereof and having its inner end above the water level, a water pipe leading into said drum, and means on the inner end of said water pipe for producing a spray of water above said pan. 7 r

In testimony whereof I aflix'my signature.

merely for the purposes of exemplification since in actual practice-it attains the features of advantage enumerated as desirable in the statement of the invention and the above de scription. 7

It will be apparent thatchanges in the details of construction, and in the combination and arrangement of parts may be resorted to Without departing from the spirit or' scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is: I

V 1. An apparatus of the class described in eluding a drum forined in two sections, a water pan interposed between the sections, a

conduit for productsof combustion passing through the drum above the pan, cold air I intake means associated with the drum at the bottom thereof and hot air take off means associatedwith the top of the drun;1,said conduit comprising a pipe extending through one sideof the drum and being offset down wardly intermediate its ends to extend through the opposite side of the drum and having a closure at last mentioned opening and a pipe rising from the lower portion of the conduit through the top of the drum.

2. In combination with a stack and a furnace, a drum separable from and arranged between the furnace and stack, a pipe extending through the drum and connecting thestack and furnace and consisting of a plurality of angularly arranged sections for1ning a tortuous passage for the products of combustion, an open top water pan arranged 'inthe drum in proximity to one of said pipe sections, a cold air pipe extending into the drum and having an upwardly directed inner end extending through and terminating above the bottom of said water pan, a water pipe leading into saididrum above the water pan, means on the inner end of said water pipe for producing a. spray of water, and a pipe extending upwardly from the drum for conveying hot air to a hot air register. 1

I 3. In combination with a furnace and a stack, a drum, a water pan in the drum, a

pipe extending through the drum and connesting the furnace and'stack, said pipe hav-' ing a part thereof in close proximity to the water pan, pipes extending from the drum for conveyin hot air tohot'air registers; a cold air con uit entering the drum adjacent
